Older versions of the CX31993 driver are known to cause high Deferred Procedure Call (DPC) latency. This manifests as audio stuttering (clicks and pops) and, in severe cases, system-wide micro-stutters during mouse movement or typing. This is often caused by inefficient polling routines within the vendor driver.
